Project history
Architected and implemented core infrastructure across the TaxMate and GigFlow platforms, enabling scalable AI and automation workflows. Designed modular microservice architecture integrating OCR pipelines, RAG-based LLM agents, and AI-driven tax document parsing using LangChain and OpenAI APIs. Engineered database schemas and ETL pipelines to unify data from gig-platform APIs. Built robust APIs using FastAPI and Node.js (TypeScript), contributed to React and React Native interfaces, and deployed distributed services via AWS, Docker, and GitHub Actions.
Designed, built, and optimized server-side systems powering a cross-platform fitness application supporting workout tracking, progress monitoring, wearable integrations, and AI-driven fitness recommendations. Built scalable FastAPI backend services with REST and GraphQL endpoints, integrated Stripe for subscriptions and billing, developed AI-powered recommendation logic using OpenAI API, and designed optimized PostgreSQL schemas.
Built and optimized server-side systems supporting a booking, scheduling, and membership management application. Developed and maintained Laravel/PHP backend services with scalable RESTful APIs, integrated third-party payment gateways (Stripe, PayPal, Mollie), built real-time notification modules using Firebase Cloud Messaging, optimized MySQL database schemas, and collaborated with mobile and product teams in Agile sprints for App Store and Google Play releases.
